Abstract: The mid-infrared laser in the range of 2–5m has been developed to apply to the fields of remote sensing, ranging, envi-
ronmental monitoring, biological engineering and medical treatment, etc.. Luminescence emission from the rare-earth ions in chalco-
genide glass fiber which was pumped by solid-state laser is an effective and direct way to obtain the mid-infrared laser in the region of
2–5m. This review represents the recent development on the studies of rare-earth doped chalcogenide glass for mid-infrared lumi-
nescence abroad and analyzed the factors influencing the mid-infrared luminescence in chalcogenide glass. Further studies on this
aspect were mentioned and prospected.
